Access control is an important security issue for the web. However, exiting methods still have some limitations. Most of them can not satisfy the requirements of loosely-coupled and fine-grained access control at the same time. This paper addresses this issue for web information system by proposing a novel access control method based on HTTP data stream filtration. It is loosely-coupled with web information system, so it is flexible and can be used in different web information systems. By the element-level resources identification algorithm we proposed, it also can achieve fine-grained access control for web page resources. In the end, the analysis of our algorithm is given. The results show that our algorithm is effective and the time-consuming is tolerable.
